World Cup upsets: biggest shocks
June 3, 2026 · 19:00 7 min read 9 views
We've analysed data from USA 1994 onwards to see how and when classic upsets take place – and what that could mean for this year's competition. This year, the biggest ever World Cup will feature 48 teams, an increase from 32, opening up the tournament to even more surprises and shocks. The World Cup draw has given rise to classic underdog victories over the years, from an amateur USA team's shock defeat of then-favourites England in 1950 onwards. But what do the numbers tell us about upsets in football's modern era?
Starting from the launch of the Fifa men's world ranking system in 1993, we have examined each World Cup match in which a lower-ranked team beat a higher-ranked opponent, along with the ranking disparity between the teams: the bigger the gap, the higher the upset score. Upsets are marked in red, while matches decided on penalties have a white border.
This World Cup was marked by a consistent stream of upsets, particularly in the group stages, with a couple of surprise regional rivalries including Belgium, ranked 27, triumphing over the Netherlands, ranked 2, and Saudi Arabia, in their World Cup debut, seeing off Morocco.
The first World Cup after the dissolution of the USSR featured the first appearance by a unified German team and arguably the tournament's most iconic underdog moment, when Yordan Letchkov's header secured Bulgaria's victory over top-ranked Germany in the quarter-finals. Bulgaria enjoyed a strong competition overall, including beating Argentina in the group stages and a surprise round of 16 win against Mexico in a penalty shootout.
This was one of the few recent World Cups to culminate in an underdog victory, as hosts France, ranked 17, thrilled a Stade de France packed with home fans when they beat the top team, Brazil, 3-0. The team's historic victory was secured with two spectacular headers from Zinedine Zidane.
The biggest upset, however, was from Nigeria, ranked 74, who beat Spain, ranked 15, 3-2 in the group stages, as well as conquering Bulgaria, ranked 35, 1-0. There were also unpredictable quarter-finals, as Croatia, ranked 19, knocked Germany, ranked 2, out of the tournament, while the Netherlands, ranked 25, saw off Argentina, ranked 6.
The hosts, South Korea, ranked 40, were the tournament's champion underdogs, making it all the way to the semi-final via victories over Poland, Portugal, Italy, and Spain. But perhaps the most significant upset came in the opening game when World Cup first-timers Senegal, ranked 32, took on the reigning champions, France, ranked 3. Senegal scored half an hour in, then defended successfully against a much older French team – including stars Zidane, Marcel Desailly, and Fabien Barthez – which struggled in Seoul's heat and humidity. At the final whistle, crowds back home in Dakar erupted in shock and joy as the former colony triumphed over the one-time imperial power.
Germany 2006 wasn't memorable only for Zidane's notorious head-butt on Marco Materazzi in the final between France, ranked 8, and Italy, ranked 13. The numbers show it was the most surprising World Cup in recent history, with 21 upsets throughout the tournament, and five in its later stages – including Ukraine's round-of-16 victory over Switzerland at their first World Cup. Other countries making their debut included Angola, Ghana, Côte d'Ivoire, Trinidad and Tobago, and Togo, making this an underdog-rich tournament.
